About a month ago I got a brazilian wax job but this time she did my anal area. I've never had it done before and now there's a lump right at my anal opening. It's not painful for BM's. In fact, it's a little itchy. I've looked at it and it doesn't look like a regular in-grown hair (usually look like pimples) but how can I tell if it's just an in-grown hair, or something like a hernia or hemroids?
